Dont know HTML have no clue what im doing in flask.

First question. Is this homework trying to get me to make a list before I start running a for loop through it?

Second... am I doing the html portion right by simply opening and closing a list <li></li>?

Third... is this for loop correct? I've also tried print dict(option.items())['name'].

app.py 
from flask import Flask, render_template

from options import OPTIONS

app = Flask(__name__)


@app.route('/')
def index():
    return render_template('options.html', options=OPTIONS)

for option in OPTIONS:
    print option.items()[0]
templates/options.html 
<ul>
<li>
  </li>
</ul>

Hi! The code challenge is asking you to use a Flask templating for loop. It wants you to loop through the options being passed into the template inside of the index function. All you need to do is create the loop notation inside of the HTML file, so you don't need to add anything to the python file app.py.

The video before this code challenge shows an example of writing the for loop at the beginning. Here are some examples from the documentation too.

I also highly suggest checking out the prerequisites for this course if you haven't already. They include some HTML courses.

At around 3:43 in the video actually shows an example that is closer to the format asked for in the challenge. The bit I couldn't figure out and still can't is why I couldn't write {{ option }} and get the result. Instead I had to write it as {{ option.name }}. That is not covered or explained in the video.

I figure it's just the teacher trying to confuse us even more than he already has :P
